Combining the convenience of a duffle bag with the waterproof integrity of a dry bag, the Zip Duffle is built with the same kind of zipper used on dry suits. The zipper runs diagonally across the top for quick access and has a vinyl flap for added protection. Webbing handles stay together with a Velcro grip, and convenient end handles make ship-to-shore transfer easy. Its low-profile shape is great for close quarters; the Zip Duffle 40 even fits through the back hatch of most kayaks. Also great for motorcycle touring and riding on outside luggage racks regardless of the weather.
